Created attachment 132302 [details] hwinfo output Hi, My Arch system seems to be crashing with the same issue, here twice in a row. Although it's a specific distro (Arch), I think it's a relevant bug, it seems to affect the Kernel, Arch doesn't mess around with the Kernel, and it's a serious bug (NULL ptr deref), and I have two independent traces. See below.
